Since 1998, Lawrence University Professor Bart De Stasio has led a Marine Term trip to Grand Cayman Island in the Western Caribbean. The objective of this trip has been to document abundance and diversity of fish species, provide evidence towards the health of coral reefs surrounding the island, and to understand the ecological relationships between the fish and coral reef environments. To accomplish this, students on the trip used Reef Environmental Education Foundation (REEF) specification to collect data on 246 fish species at 12 different coral reefs. On each dive, data collection lasted approximately 20 to 50 minutes depending on diver air consumption and non-decompression limits (Timpe, 2018). One of the key variables related to the abundance and diversity of fish was Density Index (Den).
Den was recorded as a measure of how many of a certain species was present at each site during each dive. Ultimately, the scale of Den ranged from 0 to 4, and each whole number represented a REEF category of density. These four categories were Single (S), Few (F), Many (M), and Abundant (A). A Den score of 1 corresponded to S, 2 corresponded to Few, 3 represented Many, and the highest score of 4 was Abundant. Since there were often several dives at a single site, the Den scores for an individual species were averaged to calculate an overall Den for that site each year. REEF provides an outline for performing this calculation and for understanding the specification for each of the four categories. This outline can be seen in the image below.
As I
proceed, I will perform a statistical analysis, using methods like the
T-Test, to describe important details about similarities and difference
in DENSITY_INDEX for these fish species. Additionally, I will use linear
mixed effect models, since the data is recorded longitudinally, to
investigate both how species density has changed within each dive site
and how species density has changed between the dive sites. Finally, I
will build a machine learning model to best predict a fish species based
on OOBE/RMSE comparison metrics. This will allow future researchers to
understand under what conditions they may expect to find a certain reef
species. Collectively, these results will help explain the ecology of
coral reef fish species on Grand Cayman Island.
Initially, data consisted of 246 rows and 95 columns. However, the
data set was not in tidy form as information on one variable, Density
Index, was spread across many columns. These columns were also labeled
by year and location, which meant they needed to be separated into
individual variables. To tidy the data, I used the concepts of pivoting
and separating. First, I made the Density Index variable (DENSITY_INDEX)
using the pivot_longer function. This function condensed
the columns into one hence making the data set “longer”. Next, I used
the seperate function to make individual variable columns
for the location and year each observation was collected. Finally, YEAR
was coded as a character variable and I changed it to numeric. After
this, the data set consisted of 22,632 rows and 5 columns. However, some
of the Density Index values followed an outdated version of the REEF
scale. So, values greater than the 4.0 threshold were removed.
## # A tibble: 6 x 6

## 4 Blue Angelfish 1 1998 SC 0 Deep
## 5 Blue Angelfish 1 1998 TF 0 Deep
## 6 Blue Angelfish 1 2000 CP 0 Deep
The head function shows that the five variables consist
of two character variables in SPECIES_NAME and LOCATION, and three
numeric variables in FISH_ID, YEAR, and DENSITY_INDEX. Overall, 12
locations were studied throughout the duration of data collection. These
sites include, from southeast clockwise to northeast, Bodden Bay Lagoon
(BL), Beach Bay (BB), Smith’s Cove (SC), Sunset House (SH), Sea View
(SV), Casuarina Point (CP), Devil’s Grotto (DG), Eden’s Rock (ER),
Cemetery Reef (CR), Turtle Farm (TF), Spanish Bay (SB), and Mangroves
(MG). A majority of these sites were described and shown geographically
in 2018 by Alec Timpe, a Marine Term student of Professor De Stasio. His
dive site image and site description paper can be seen below.

TWO PART MODEL: A Specialized Mixture Model
why?
A two-part model is a flexible statistical model specifically designed to deal with limited dependent variables. The distinguishing feature of these variables is that the range of values they may assume has a lower bound occurring in a fair number of observations.
How?
The zeros are typically handled using a model for the probability of a positive outcome:
φ(y > 0) = Pr(y > 0|x) = F(xδ)
where x is a vector of explanatory variables, δ is the corresponding vector of parameters to be estimated, and F is the cumulative distribution function of an independent and identically distributed error term, typically chosen to be from extreme value (logit) or normal (probit) distributions
For the positives, the model is usually represented as:
φ(y|y > 0, x) = g(xγ)
where x is a vector of explanatory variables, γ is the corresponding vector of parameters to be estimated, and g is an appropriate density function for y|y > 0
